v0.5.2: move veilor-installer + veilor-firstboot to /usr/local/bin

QEMU boot test of v0.5.1 (commit 1c99ae0) revealed both scripts
missing from /usr/local/sbin/ on running system, despite being in
overlay/usr/local/sbin/ in the source tree.

Root cause: Fedora's filesystem package (or post-install scriptlet)
rewrites /usr/local/sbin → /usr/local/bin symlink AFTER kickstart
%post --nochroot's overlay copy runs. The cp -a placed files in
/usr/local/sbin/ as a real directory; the symlink replacement
deleted them.

Confirmed via tty diagnostic: `ls -la /usr/local` shows
`lrwxrwxrwx ... sbin -> bin` with bin mtime predating sbin symlink
ctime by ~5min — overlay copy ran first, scriptlet rewrote sbin
second.

Fix: move both binaries to overlay/usr/local/bin/ where they're
safe from the symlink rewrite. Update all references:
- kickstart/veilor-os.ks chmod path + chown + diagnostic ls
- overlay/etc/systemd/system/getty@tty1.service.d/veilor-installer.conf ExecStart
- overlay/etc/systemd/system/veilor-firstboot.service ExecStart
- scripts/selinux/build-policy.sh fcontext + restorecon paths
- generated install ks template inside veilor-installer

Service drop-in stays at /etc/systemd/system/getty@tty1.service.d/
unchanged. The veilor-installer binary in /usr/local/bin/ is
discoverable via $PATH same as before.
